Abstract
This paper takes the Shenzhen-Zhongshan Link as the research subject and systematically explores the planning and research approach,investigation and design methods,organizational management model,and innovation pathways for major cross-sea corridor projects,considering its complex construction conditions,functional requirements,and development objectives.As a super cluster project integrating bridges,artificial islands,tunnels,and underwater interchanges,the Shenzhen-Zhongshan Link faces four major technical challenges:"large-scale,soft foundations,extreme heights,and complex interferences".These include enormous traffic demand,construction on extremely soft ground,wind-resistant design for ultra-high bridge decks,and the complexity of multi-node traffic connectivity.
The paper proposes a problem-oriented approach,employing systems thinking and cluster-based strategies to resolve key technical difficulties,while using engineering philosophy to reveal the mechanisms influencing the entire lifecycle of such mega-projects.During the planning and research phase,the study emphasizes the importance of multi-corridor analysis,evaluating route alignments and engineering solutions within the optimal corridor through comprehensive assessment,and ultimately recommending the best implementation plan based on a systems theory framework.
In terms of investigation and design,the Shenzhen-Zhongshan Link adopts standardization,prefabrication,intelligence,and integration as core methodologies.It transcends traditional single-project thinking by establishing a cross-disciplinary,systematic design philosophy and strengthening the synergy between design and construction to leverage the advantages of various specialized resources.The paper provides a detailed analysis of the project's investigation,design organization,and management,highlighting that forming interdisciplinary teams,employing joint design models,and innovating in design-construction integration can effectively tackle technical challenges,shorten schedules,and reduce costs.
Regarding key solutions and comparative analyses,the study discusses overall alignment optimization,landscape design coordination,and innovative approaches at bridge-tunnel transitions.For instance,the Shenzhen-Zhongshan Link adjusted its alignment to meet navigation and aviation height restrictions while using unified styling elements to enhance aesthetic coherence.At the bridge-tunnel junctions,the removal of supports reduced bridge elevation and shortened artificial island lengths,optimizing the overall cluster project.
To address critical technical challenges,the paper advocates a problem-driven research methodology,combining epistemological analysis and experimental methods to drive innovation.Examples include wind tunnel tests to improve the aerodynamic performance of the Shenzhen-Zhongshan Bridge,the 12-hammer synchronous driving technique for rapid island formation in ultra-soft strata,and the groundbreaking use of deep-sea cement mixing piles for immersed tunnel foundations—A first in China.The paper underscores the importance of practical validation,ensuring all innovative solutions undergo simulation tests before real-world application.
Finally,the study summarizes the vital role of engineering philosophy in the Shenzhen-Zhongshan Link,demonstrating how it provides essential methodologies and conceptual tools for complex cross-sea projects.By distilling a universal framework for the planning and construction of cross-sea corridors,the Shenzhen-Zhongshan Link's engineering practice offers theoretical foundations and practical references for future projects of similar scale,while setting a new global benchmark for cross-sea infrastructure development.关键词
